Hi,
I am currently using the EKF block for one of my simulations. As soon as I start the simulation, it shows an error as shown below:
I have double checked my R matrix and it contains values but for some reason EKF block is throwing an error saying it is empty.
A quick Internet search regarding this issue returned nothing.
Any guidance on this would be helpful
Thanks,
Suraj

It would be beneficial for us if you share your model so that we can analyze it.

As mentioned in the above problem I understand that the R matrix is not empty while running the EKF Block for the simulation. The issue might be encountered due to the license and hence you can check using the below code:
% Check if Control System Toolbox is licensed
if license('test', 'Control_System_Toolbox')
disp('Control System Toolbox is licensed.')
else
disp('Control System Toolbox is not licensed.')
end
